Discreensd Maf!
I discreened the MAF because I came across one for 20 bucks 
I think it came out of an Iroc or something. But I bought it and discreened it! 
And the gains were amazing I think for a free mod! My car is a 1986 automatic and also has K&N, Cut Air Lid, TB Bypass, Mild cam, .030bore, forged pistons, clevite bearings, Roller timing chain, Msd wires, Magnaflow High flow cat, lt mufflers, and a rebuilt tranny! Before it was fast but now I can be cruzin and at about 15mph and floor it and the tires will chirp at the point of down shift! 
Im Happy!

Also the removal of a significant restriction, ie reduced cross-section, helps too.......more than a placebo....
It depends, but somewhere around 5 hp gain is probably realistic..
My screen is gone....no SOP when I removed it......no before and after dyno......no before and after track times......but visually it was a good thing to do......and again I doubt, but don't know for sure, whether it screwed up my laminar flow......but my motor does run pretty good!!
A great mod considering it is FREE!! but just my humble opinion...

this intake tract thread is cotroversial to say the least.the cut lid,k&n vs. paper,and the maf screen removal debate is interesting and deserves another shot.is it possible there was a problem with the original maf with the screen? i would never ? a members post of performance gains,thats what this forum is here for.is the screen to catch "debris" in case of a broken filter or plastic housing?how can debris large enough to be caught by the screen make it past the filter?if the screen was condensed,what would the actual area be?1/4 inch or 2 inches for example.just wondering.junior

This article posted a few days ago says that removing the screen will help increase air flow. http://www.corvettemagazine.com/2000...ldup/l98p1.asp
Note that it was part of additional mods including K&N filter.
